Answer:

The area of the shaded region= 37.68

Step-by-step explanation:

Area of the outer circle= 2* 3.14* 36                 (Area of the circle=2\pir)

                                        =113.04

Area of the inner circle=2*3.14* 12

                                       =75.36

Area of the shaded region= Area of the outer circle- Area of the inner circle

                                             = 113.04- 75.36

                                               =37.68

The product of two numbers is 30. If one of the numbers is 15/, what is the other number?
PSYCHO15rus [73]

Answer:

The other number is 2 if the given number is 15.

Step-by-step explanation:

One of the numbers is 15, correct?

Let the other number be x.

15 × x = 30

x = 30/15

x = 2.

Let's check:

15 × 2 = 30.

30 = 30.

Correct!

Worker A finishes the job in 10 hours; worker B finishes it in 12 hours, and worker C finishes it in 15 hours.
nika2105 [10]
A=1/10, b=1/12, c=1/15  (these are the rates for each worker...)

1.)

2(1/10)+4(1/12)+t/15=1

1/5+1/3+t/15=1

(3+5+t)/15=1

3+5+t=15

8+t=15

t=7

So it would take c 7 hours to finish the job.

2.)

1/40-1/60

(3-2)/120

1/120

The drain rate is 1/60.  So you will need to find t when the tank is empty, while starting at 2/3 capacity...

2/3-t/60=0

(40-t)/60=0

40-t=0

t=40

It would take 40 minutes to empty the tank when it is 2/3 full.
